Teach Siri new tricks

We're not the biggest fans of Siri (we even made a list of 9 things we wish it could do). But so many jailbreak apps help bring out its full potential -- change voices with AnyVoice, teach it to shut down or restart your phone with VoiceUtils, or if you don't have Siri you can install Sara, a jailbreaker's alternative.

Use a Swype-style text input

We like the Swype text input method, usually only available on certain Android phones. You can drag your finger over over the keyboard and it recognizes the character you want to type when you change direction. The iSwipe app brings this same functionality to your liberated phone.

Access all your major settings with one button

We love the jailbreak plugin SBSettings, which gives you instant access to all your important settings with nothing more than a double-tap on your home button, though you can configure the menu to appear as a result of any button or gesture combo you like.

Play Nintendo games!

Install iMame and play Nintendo ROMs that would never see the light of day in the iTunes App Store.

Turn your iPhone into its own security system

iCaughtU is a jailbreak app will take pictures of whoever attempts to enter the incorrect password to use your phone. You can set it up to email the photos to yourself when it catches a thief. Handy!

Get rid of notifications without unlocking your screen

Ipsum is an app that lets you swipe over notifications to make them go away without opening the app that generated the notification. It's perfect for people who like to keep a clear Notification Center.
